// GTMHTTPFetcherService.h
//
// The fetcher service class maintains a history to be used by a sequence
// of fetchers objects generated by the service.
//
// Fetchers that do not need to share a history may be generated independently,
// like
//
// GTMHTTPFetcher* myFetcher = [GTMHTTPFetcher fetcherWithRequest:request];
//
// Fetchers that should share cookies or an ETagged data cache should be
// generated by a common GTMHTTPFetcherService instance, like
//
// GTMHTTPFetcherService *myFetcherService = [[GTMHTTPFetcherService alloc] init];
// GTMHTTPFetcher* myFirstFetcher = [myFetcherService fetcherWithRequest:request1];
// GTMHTTPFetcher* mySecondFetcher = [myFetcherService fetcherWithRequest:request2];
